2003 Acura 3.2TL BaseFACTORY OEM SERVICE PROCEDURE

Yaw Rate

"Offset" is reference voltage or standard within the rate sensor. It should indicate 1.500 to 3.500V with the vehicle stopped.

"Sensor" indicates the voltage output from the yaw rate sensor. It should indicate 1.500 to 3.500 V with the vehicle stopped.

A "Sensor" output voltage HIGHER than that of the "Offset" voltage indicates the vehicle is turning to the RIGHT.

A "Sensor" output voltage LOWER than that of the "Offset" voltage indicates the vehicle is turning to the LEFT.

With the vehicle stopped, sitting still with the engine idling, both the "Offset" and "Sensor" voltages should be within 0.01 V +/- of each other.

If not, replace the Navigation unit.

Example:

NOTE: The vehicle is stopped, sitting still, with the engine idling.

Good Offset 2.517 V

Sensor 2.517 V (0.010 V +/- )

Bad Offset 2.517 V

Sensor 2.823 V

NOTE: Do not try to tune the yaw rate sensor unless instructed by American Honda.
